Changing of port Admin State doesn't work correctly

[Ilya Bumarskov]

Fuel 9.1 with NSX-t plugin 1.0.0 build#10.17.2016

Steps to reproduce:
   - Create env with vCenter and DVS plugin
   - Add following nodes:
         * Controller
         * Controller
         * Controller
         * Compute, cinder
         * Compute-vmware, cinder-vmware
   - Configure VMware vCenter Settings. Add 2 vSphere clusters and configure Nova Compute instances on controllers and compute-vmware.
   - Deploy env
   - Login to Horizon
   - Create instance run ping to external net (ping 8.8.8.8)
   - Navigate to Admin > System > Networks
   - Choose any netwrok
   - Try to change admin state for port

Observed behaviour:
There is three various scenarios
1) If port was attached to instance after changing state it becomes "deatached"
2) If port was attached to dhcp it becomes "deatached" and new port with "network:dhcp" attached device will be created.
3) If port was attached to router_interface we can't change admin state (Error: Failed to update port)

Looks like there is a limitation in NSX Manager which does not allow to change logical port state.
